You're right that "autopilot" isn't the state of the art anymore. It's just radar cruise control and automatic lane keeping. The radar cruise control feature is already available in the Model S, and has been for a couple of months. Lane keeping is the missing piece. You can buy cars right now with automatic lane keeping, and Tesla has demoed it extensively in their cars, so there's no real doubt about it coming soon to Tesla.

Three months is "hilarious" for a feature that's already been commercialized by others and has been shown to be nearly done in Tesla's implementation? How do you figure?
